Abstract: A three-phase PWM rectifier controlled by phase and amplitude is presented. The lagging phase angle θ between supply voltage and input voltage of rectifier and modulation are controlled with realtime detection of power factor angle and DC bus voltage. The algorithm is linearized, and decoupling control is implemeted to achieve unity power factor. The range of parameters, constraint conditions, and adjustment process of system are analyzed under load disturbance. Harmonic of the threephase PWM rectifier is also analyzed. The control algorithm is simple, and easy to implement, and verified by experiments.

Key words: decoupling control, harmonic analysis, phase and amplitude, unity power factor, PWM converters
